# '''Mohs/OneBigLie:''' Authors of works in this class invent one (or, at most, a very few) counterfactual physical laws and writes a story that explores the implications of these principles. James Blish's ''CitiesInFlight'' stories fall squarely into this category, courtesy of the "Dirac Equations" leading to the "spindizzy motor" and instantaneous communication. Most works in Creator/AlanDeanFoster's ''Literature/HumanxCommonwealth'' series, the Ad Astra board games and Creator/RobertAHeinlein's ''Literature/FarnhamsFreehold'' fall in this category, as do many of Creator/VernorVinge's books.\\

# '''Mohs/ScienceInGenreOnly:''' The work is unambiguously set in the ''literary genre'' of ScienceFiction, but ''scientific'' it is not. AppliedPhlebotinum is the rule of the day, often of the [[ItRunsOnNonsensoleum Nonsensoleum]] kind, GreenRocks gain NewPowersAsThePlotDemands, and both BellisariosMaxim and the MST3KMantra apply. Works like ''WesternAnimation/{{Futurama}}'', ''Anime/TengenToppaGurrenLagann'', The Creator/{{DC|Comics}} and Creator/{{Marvel|Comics}} universes,[[note]]although the individual comics of some heroes might fit elsewhere occasionally[[/note]] and ''Franchise/TheHitchhikersGuideToTheGalaxy'' fall in this class.

Example: a character is shown a machine for traveling into the past and asks, "How does it work?"

* '''In medium SF:''' "You sit in this seat, set the date you want, and [[Film/BackToTheFuture drive to 88 mph]]."

* '''In really hard SF:''' "It doesn't. Time travel to the past is impossible." [[note]]General Relativity allows for solutions for Kerr black holes where closed timelike curves, and therefore time travel, are possible. It is expected that a proper theory of Quantum Gravity will remove this possibility.[[/note]]

# '''Mohs/WorldOfPhlebotinum:''' The universe is full of AppliedPhlebotinum with more to be found behind every star, but the Phlebotinum is dealt with in a [[MagicAIsMagicA fairly consistent fashion despite its lack of correspondence with reality]] and, in-world, is considered to lie within the realm of scientific inquiry. Works like Creator/EEDocSmith's ''Literature/{{Lensman}}'' series, ''Anime/NeonGenesisEvangelion'', ''Series/StarTrekTheOriginalSeries'', and ''Franchise/StarCraft'' fall in this category.\\

''Note 7:'' When adding this trope to a work page, [[Administrivia/TypeLabelsAreNotExamples don't simply put down the number and leave it at that]]. This would require a troper to visit this page to learn more about it. That's fine if the troper is interested, but if they are already working down the work's page (and only at the M's), they probably don't want to wander off on a WikiWalk. You can say the number, but please go on a bit explaining what the number is. For instance:

''Note:'' The works mentioned below are sheerly for illustrative purposes -- please add new examples to the subpages.

# '''Mohs/SpeculativeScience:''' Stories in which there is no "big lie" -- the science of the tale is (or [[ScienceMarchesOn was]]) genuine speculative science or engineering, and the goal of the author to make as few errors with respect to known fact as possible. The first two books in Robert L. Forward's ''Rocheworld'' series and Creator/RobertAHeinlein's ''Literature/TheMoonIsAHarshMistress'' fall in this class.\\

* '''In hard SF:''' "A good question with an interesting answer. [[{{Infodump}} Please have a seat while I bring you up to speed]] on the latest ideas in quantum theory, after which I will spend a chapter detailing an elaborate, yet plausible-sounding connection between quantum states, the unified field theory, and the means by which the brain stores memory, all tied into theories from both UsefulNotes/AlbertEinstein [[SmallReferencePools and]] StephenHawking."

''Note 4:'' Sometimes a study hits the news that, if confirmed, would reassign many works on the scale. For example, [[http://www.telegraph.co.uk/news/science/8782895/CERN-scientists-break-the-speed-of-light.html the September 2011 OPERA experiment which measured faster-than-light travel by neutrinos]] might have moved works whose Mohs/OneBigLie was FTLTravel into the Mohs/SpeculativeScience category. There are three reasons to be cautious about doing so: first, because mass media reporting of scientific results is often inaccurate due to the difficulty of presenting technical results to a non-technical audience; second, because revolutionary new results (and results in the ''news'' are generally new) are far more likely to be overturned than they appear (indeed, the OPERA anomaly was [[http://www.sciencemag.org/news/2012/02/breaking-news-error-undoes-faster-light-neutrino-results caused by faulty equipment]]); and third, for purposes of the Scale, the yardstick of scientific plausibility is what the science said ''at the time the work was written'', not what [[ScienceMarchesOn scientists discovered later]].

''Note 7:'' Keep in mind that ScienceMarchesOn when categorizing older works. If the story in question was based on a scientific model that, while now discredited, was widely accepted in its day, it still qualifies as "hard" science fiction because the author [[FairForItsDay did his best]] ''[[FairForItsDay with the information available at the time]]''.

''Note 8:'' When adding this trope to a work page, [[Administrivia/TypeLabelsAreNotExamples don't simply put down the number and leave it at that]].

* '''In medium SF:''' "You sit in this seat, set the date you want, and [[Film/BackToTheFuture drive to 88 mph]]."

* MohsScaleOfScienceFictionHardness: 5. This work leans heavily into Mohs/SpeculativeScience -- the science of the tale is (or was) genuine speculative science or engineering, and the goal of the author to make as few errors with respect to known fact as possible.

A subclass of this (5.5 on the scale) is ''Futurology:'' stories which function almost like a prediction of the future, extrapolating from current technology rather than inventing major new technologies or discoveries. (Naturally, {{Zeerust}} is common in older entries.) ''Film/{{Gattaca}}'', Manga/{{Planetes}}, ''TabletopGame/TranshumanSpace'' and the more SpeculativeFiction works of Creator/JulesVerne fall in this subclass.

# '''RealLife''' (aka Fiction in Genre Only): A SharedUniverse which spawned its own genre, known as "NonFiction". Despite the various problems noted at RealityIsUnrealistic, it is almost universally agreed that there is no other universe known so thoroughly worked out from established scientific principles. [[UsefulNotes/{{NASA}} The Apollo Program]], WorldWarII, {{a|rsonMurderAndJaywalking}}nd {{Woodstock}} fall in this class.

# '''Mohs/ScienceInGenreOnly:''' The work is unambiguously set in the ''literary genre'' of ScienceFiction, but ''scientific'' it is not. AppliedPhlebotinum is the rule of the day, often of the [[ItRunsOnNonsensoleum Nonsensoleum]] kind, GreenRocks gain NewPowersAsThePlotDemands, and both BellisariosMaxim and the MST3KMantra apply.

# '''Mohs/PhysicsPlus:''' Stories in this class once again have multiple forms of AppliedPhlebotinum, but in contrast to the prior class, the author aims to justify these creations with [[ShownTheirWork real]] and [[MinovskyParticle invented]] natural laws -- and these creations and others from the same laws will [[ChekhovsBoomerang turn up again and again in new contexts]]. Works like ''Webcomic/SchlockMercenary'', DavidWeber's ''Literature/HonorHarrington'' series, David Brin's ''Literature/{{Uplift}}'' series, and ''Series/BattlestarGalactica2003'' fall in this class. Most RealRobot shows fall somewhere between Classes 2 and 3.

A subclass of this (5.5 on the scale) is ''Futurology:'' stories which function almost like a prediction of the future, extrapolating from current technology rather than inventing major new technologies or discoveries. (Naturally, {{Zeerust}} is common in older entries.) ''Film/{{Gattaca}}'', Manga/{{Planetes}}, ''[[http://en.wikipedia.org/wiki/The_Machine_Stops The Machine Stops]]'' by E. M. Forster, ''[[http://en.wikipedia.org/wiki/Transhuman_Space Transhuman Space]]'' and the more SpeculativeFiction works of Creator/JulesVerne fall in this subclass.

''Note 3:'' While the term "soft science fiction" is used above as the antonym of "hard science fiction", another common use of the term is to describe ''soft science'' fiction: [[AsimovsThreeKindsOfScienceFiction sociological and psychological]] science fiction. This can, in some cases, make it appropriate to talk about "hard soft science fiction", but doing so is likely to confuse people. By and large, though, science-fiction "hardness" doesn't correlate well with realism in areas such as characterization, views of human nature, or views of human societies. In such areas, some works that barely qualify as SF might be unsparingly realistic ... and some of the hardest SF imaginable might deal in out-and-out fantasy.

A subclass of this class (arguably 2.5 on the scale) contains stories that are generally sound, except the physics aren't our own. Plot aside, they are often a philosophical exploration of a concept [[ScienceMarchesOn no longer considered true]] (such as [[{{Creator/Aristotle}} Aristotelian physics]]), or never considered true in the first place (e.g. two spatial dimensions instead of three). Some of Creator/ArthurCClarke's stories fall here. However, given [[ScienceFantasy the overlap with fantasy]], it can [[GenreBusting prove tricky]] to even classify a story as SF.

* '''In hard SF:''' "A good question with an interesting answer. [[{{Infodump}} Please have a seat while I bring you up to speed]] on the latest ideas in quantum theory, after which I will spend a chapter detailing an elaborate, yet plausible-sounding connection between quantum states, the unified field theory, and the means by which the brain stores memory, all tied into theories from both AlbertEinstein [[SmallReferencePools and]] StephenHawking."

Unfortunately for analytical purposes, this pattern is not universal - hard SF stories can skip over the details as long as the basic explanation is correct [[MagicAIsMagicA given what's been established so far]]. Therefore, regardless of the [[http://web.archive.org/web/20091216091121/http://www.shrovetuesdayobserved.com/flight.html typical stylistic flourishes]] of hard SF, the only way to define it is self-consistency and scientific accuracy.

''LightNovel/BodaciousSpacePirates'' has two big lies(FTL and artificial gravity, which the story is exploring and extensive thought and notification of unrealism was given in the afterword) and a few small fibs(usually enlarged versions of nanoscopic physic concepts that appear as chapter only gadgets, like the cooling beam gun used as a stun gun which in all sense is not important to the plot.) and falls between 3 and 4.
